Explains how to assemble and use a tripod to move heavy loads in the backcountry. The tripod's legs are just 6 feet long, allowing it to be packed by a horse or mule. The tripod was developed by the Bitterroot National Forest. The Missoula Technology and Development Center prepared a mechanical drawing (No. 1035) that would allow a welder to fabricate the tripod.
